Here is a list of plugins that are known to be problematic in SketchUp. The purpose of the list is to provide a central resource to track buggy plugins. This will hopefully reduce some the many hours of frustration experienced by users, authors, and supporters of plugins. It goes without saying that if you install a quarantined plugin, you're going to have a bad time.

There may be several reasons that a plugin may end up in quarantine:

It crashes SketchUp.

It changes the behavior of SketchUp in a way that is indistinguishable from a bug.

Did the Quarantine list become smaller? I remember a lot more plugins in this list. I had a question about a plugin that was quarantined, quarr_jsalign.rb and I was wondering just why this plugin was quarantined.

I use this plugin all the time. To drop component/Group to a set elevation and just wanted to make sure just what it was doing to my Sketchup program.

Now, I see the list is shorter and doesn't include this plugin. Am I looking in the right place or has the list been modified.
